IMPROVEMENT IN HORSE-CLIPPERS.

vSpecification forming part of Letters Patent No. 210,909, datedDecember 17, 1878;

application filed September 27, 1877 patented in England, February 25,1874.

To all whom it may concern Be it known that I, WILLIAM BOWN, ofBirmingham, England, have invented certain Improvements inHorse-Clippers, of which the iellowing is a specification:

One of the objects of this invention is to simplify the construction ofhorse-clippers by doing away withmany of the loose parts, which areliable to become detached and lost, thereby rendering the instrumenttemporarily useless.

Another object of my invention is to so construct the parts as toprevent the instrument from being clogged by hair and dirt, which, ifnot removed, will injure the cutting-edges and otherwise derange theapparatus.

In the accompanying drawings, Figure 1, Sheet 1, is a front view, andFig. 2, Sheet 1, an edge view, of my improved horse-clipper.

The fixed serrated or toothed cutter-plate c is secured, as usual, byscrews or rivets to the stem. of one of the handles b N, and upon itslides the movable toothed cutter-plate c, the latter being slotted, asshown at c c in the detached views, Figs. 3 and 3", in order to receiveguidepins which project from the inner face of a T-piece or clampingbar,d, which is secured to the fixed cutter c by means of a screw-bolt, aand win g-nut a", or thumb-screw.

The T-shaped clamping-bar (1, whereby the movable cutter c is held inplace, is shown detached in front and edge views, Figs. 4 and 5, Sheet1, and through the center of this clamping-bar passes the screw-bolt a,which is intended to receive the clamping-nut a Projectin g inward fromthe tail end of the T-piece (l is a stud-pin, d Figs. 4 and 5, whichpasses through a hole, b in the movable or propelling handle I), andenters a hole in the fixed cutter-plate a, and thus forms afulcrum forthe movablehandle 0 The stem of this handle carries at its upper end ashort proj ectin g arm, 0", which enters a notch or recess, 0 made inthe movable cutter-plate c, and serves to impart a reciprocating motionthereto. The

clampingnut bears on the back of the T- shaped clamping-bar near themiddle, and by this arrangement the clamping-bar d, while being screwedup, will be caused to adjust and equalize its pressure upon the movingcutterplate 0, thereby rendering this part of the instrument self-adjustin Fig. 6, Sheet 2, is a back view, and Fig. 7, Sheet 2, a frontview, of a modification of the horse-clipper just described, theT-shaped clamping-piece having been removed in order that the joint maybe more clearly seen. Fi 8, Sheet 2, is a section of the same.

In this case the principal working parts are constructed very much inthe same manner as those shown at Figs. 1 to 5. In Fi 6, Sheet 2, areshown a number of slots, 9 9, made in the fixed plate a, and arranged inparallel lines below and in line with the teeth of the cutting-plates.The ends of the slots are chamfered or beveled outward, in order toprevent the back plate from picking up any dirt from the horses skin,and also to facilitate the discharge of any hair or dirt that may workin between the cutters.

It will be obvious that in place of the long slots shown in thedrawings, openings of other forms may be used.

In order to reduce the instrument to as few pieces as possible, and thusobviate the liability of losing small detached parts when the machine istaken to pieces, I form the upper end of the movable handle I) with aboss, 6, Figs. 7 and 8, Sheet 2, which fits into a circular countersunkrecess made either in the fixed cutting-plate c or in the head of thefiXGd han- (dle b. By this means I dispense with the use ofthefulcrum-pin and the nut, which are liable to be dropped out and lost,thereby rendering the instrument temporarily useless.

Instead of securing the cutting-plates by means of a nut and screw-boltpassed through them and the T-shaped clamping-piece d, I effect thisobject by means of a simple thumbscrew, f, which screws into a holetapped in the fixed cutting-plate c.

Instead of making the clamping bar T shaped, so that it may carry thefulcrum-pin of the movable handle, as shown in the drawings, it may bemade straight, and be held in its place by a clamping screw and nut.

By arranging the several parts of horseclippers as herein set forth, theconstruction of these instruments is much simplified. They are alsogreatly strengthened, and are ren deredless liable to derangement thanhorse-clippers of the ordinary construction. Moreover, by dispensingwith many loose parts, the risk of losing such parts and therebytemporarily dis-' can readily be done by any unskilled workman orlaborer, or even by a child, while in other constructions the puttingtogether of the parts and their adjustments generally, if not always,

requires special tools or askilled workmam Again, there is no rivetedmetal in the construction of my clipper, and consequently I avoid allshaeklin g and loosening of the parts.

I lay no claim to the parallel action of the top and bottom plates, norto the levers or handles for actuating the same; but

What I do claim isr 1. In a horse-clipper, the T-shaped device 01,constructed and applied as shown and described, its projecting pins orstuds serving, one as an axis for the movable lever to work upon, andthe others as guides to the movable cutter-plate.

2. In combination with the reciprocating plate 0, the T-shaped bar d,and a single fastening device, the plate a, constructed with a series oflong parallel slots, 9 g, chamfered or beveled outward at the top andbottom of the slots, as and for the purpose described.

WILLIAM BOWN.
